INTRODUCTION/PURPOSE: Sharp recanalization of chronic venous occlusions is usually performed with targeting of wire-capture devices like loop snares or balloons. We describe sharp recanalization of chronic venous occlusions using self-expanding stents and vascular plugs.
We retrospectively reviewed all sharp venous recanalization procedures performed over an 11-month period and found Wallstent and Amplatzer vascular plug (AVP) targeting was performed in 16 patients. Patient demographics, occlusion site, targeting device, technical success of the targeting, and overall procedural success were recorded.
Technical success was achieved in twelve (86%) Wallstent and two (67%) AVP deployments. Procedural success was achieved in 15 (94%). Three minor complications occurred.
Wallstent and AVP targeting may be a useful technique when performing sharp recanalization for chronic venous occlusions. These devices expand the target space and present the same cross section viewed from any angle and can directly capture and extract the wire, features helpful in regions with crowded vascular anatomy.
引言/目的：慢性静脉闭塞的锐性再通通常采用圈套器或球囊等导丝捕获装置进行靶向操作。我们描述了使用自膨式支架和血管塞进行慢性静脉闭塞的锐性再通。
我们回顾性分析了11个月内所有的锐性静脉再通手术，发现16例患者采用了Wallstent和Amplatzer血管塞（AVP）靶向操作。记录患者的人口统计学资料、闭塞部位、靶向装置、靶向操作的技术成功率以及总体手术成功率。
12例（86%）Wallstent和2例（67%）AVP植入操作取得技术成功。15例（94%）取得手术成功。发生了3例轻微并发症。
在进行慢性静脉闭塞的锐性再通时，Wallstent和AVP靶向操作可能是一种有用的技术。这些装置扩大了目标空间，从任何角度看都呈现相同的横截面，并且可以直接捕获和取出导丝，这些特点在血管解剖结构复杂的区域很有帮助。
